PROBLEM TO BE SOLVED: To provide a cooling tool capable of being brought into contact with a cooling object widely by freely curving as a whole along a curved surface made by the cooling object, free from inhibiting cooling effect caused by that contact with the cooling object becomes line contact or point contact, and avoiding a user to feel pain in the case of that the cooling object is the human body.SOLUTION: A plurality of cold insulator containers 6 are connected by a connection material 12 comprising a sheet-like material 13 having flexibility so as to make the cold insulator containers 6 rotatable each other to every direction in a fixed range. A cold insulator 3 is stored in each of the cold insulator containers 6. A principal part 7 of each of the cold insulator containers 6 has a shape where a cross section has bent parts 8a-8d, and cooling object contact wall surfaces 9a and 9a which are directly or indirectly brought into contact with a cooling object are in a plane shape or a curved shape with a small curvature.COPYRIGHT: (C)2015,JPO&INPIT【課題】冷却対象がなす曲面に沿って全体として自由に湾曲させ、冷却対象に広く接触させることができるとともに、冷却対象との接触が線接触または点接触となってしまい、冷却効果が阻害されたり、冷却対象が人体の場合、使用者が痛く感じることがない保冷具を提供する。【解決手段】複数の保冷剤容器6を柔軟性を有するシート状材13からなる連結材12により連結し、保冷剤容器6を互いに対して一定範囲内においてあらゆる方向に回動可能とする。各保冷剤容器6内に保冷剤3を収容する。保冷剤容器6の主要部7は、横断面が屈曲部8a~8dを有する形状とし、かつ冷却対象に直接または間接的に接触される冷却対象接触壁面9a,9aを平面状または曲率の小さい曲面状とする。【選択図】図14
